Alternatively, even cognitive can integrate to a certain degree with systems and be powerful, don't you think?
If you mean by "systems neuroscience" the circuit- and neuroanatomically-based approaches, then the cognitive people have certainly been using the systems approach for a long time, especially those working with primates.
The fundamental problem is, many meaningful experiments in cognitive neuroscience require humans or primates, in which the techniques for genetic manipulations are next to nonexistent right now. We need a big methodological breakthrough here...
